IMPROVEMENT IN FLOATS FOR HORSE-TRUGHS, &c.

Specification forming part of Letters Patent No. l, dated December 1, 1874; application led May 14, 1874.

To all whom it may concern Be it known that I, J ULIUs JoNsoN, of the city, county, and State of New York, have invented an Improvement in Float-Valves for Horse Trou ghs, Drinking Hydran ts, Water- Closets, and other purposes, of which the following is a specification:

This invention consists in a iioatvalve for regulating the level of the water. inA horsetroughs, and for other purposes, in which there is combined with the float two valves, the one of which is an elongated cylindrical valve, arranged between stops on the lioatstem in a free or loose manner, so that, while operatin g conjointly with the iioat to regulate or shut ofi' the supply, it also has an independent rising and falling motion, and in the course of its action opens and closes a supplementary passage in connection with the inlet to admit or exclude water to and from the under side of said valve. The other valve, which may be permanently connected with the ioat-stem, below, has a positive action in connection with the oat, and serves to close or open the discharge-aperture for the water admitted to the under side of the main or elongated cylindrical valve. By this combi` nation a superior pressure is brought to bear on the under side of the main valve to complete and perfect the closing of it, which, otherwise, the lioat, by the pressure on top of said valve, is liable to fail to do.

In the drawing, Figures l and 2 are vertical sections of my improved lloatvalve in different working positions, Fig. 3, a horizontal section on the line .fr cc, and Fig. 4t a similar section on the line 3/ y.

A is the main case or casting, constructed with an inlet, B, for the supply of water under pressure, and with a cylindrical chamber, C, for the main or cylindrical valve D to work up and down within, and which serves, in the course of its action, to shut oft or open communication between the inlet B and the space above said valve, whereby the supply of wa ter to the trough, through apertures b c c, is controlled, E being the seat against which said valve bears when closing supply to the trough or chamber to which the apparatus is applied, and in the water of which, or of a case communicating therewith, it is immersed. G is the iioat, which serves to buoy up and raise the valve D as the trough fills with water, and so to shut oil' the supply, the dropping of said valve with the falling of the iioat opening it again as the water diminishes in the trough. There is a liability, however, of the valve D, when lifted by the ioat, failing to perfectly close the orifice b of the valveseat E, by reason of the pressure of the water o'n the top of the valve. To remedy this, said valve D is titted loose or free on the valve-stem al between stops c c; also, the chamber G closed below, but provided with a discharge-opening, f, which is closed by a valve, H, on the lower end ofthe iioat-stem, that passes out through the openingf. There is also communication established by a passage or orice, g, between the inlet B and the chamber, which oritice is controlled by the main valve D.

The action of these parts is as follows: Supposing the parts to bein the position represented by Fig. 1, then water freely passes by the inlet B to the trough, and the orifice g is closed against water passing to the under Vside of the valve D. The lioat G at irst commences to rise freely, and does not lift upon the valve D till the stop e strikes the bottom of the latter. A further rising ofthe oat brings the valve D up into nearly close contact with the seat E, causes the valve H to close the aperture f, and the valve D to uncover the orifice g, all as represented in Fig. 2. Water from the inlet B, then entering the chamber G, below the valve D, by the oritice g, completes the raising oi' said valve, so that it effectually closes the opening b inthe valve seat E. When the water falls again in the trough, the float G, in dropping, causes the valve H to open the outlet j', and so permit of the water escaping from below the valve D, which, accordingly, is at liberty to move down again so soon as the stop c comes in contact with it.

What I claim as new, and desire to secure by Letters Patent, is

The combination of the loose elongated cylindrical valve D, the Vstops c e on the iioat-stem, the valve H, and the orifice g, ar-

ranged foroperation in relation with each other, the valve-seat E, the chamber (l, and the inlet B, substantially as specified.
